atherosclerotic heart disease
atherosclerotic heart disease - a chronic indolent lesion of the coronary arteries, resulting from occlusion of their lumen until the complete obstruction due to the formation of cholesterol deposits.The result of the above the coronary arteries is the inhibition of trophism of the cardiac muscle and, therefore, disturbance of the basic functions of the heart.
Fortunately, atherosclerotic heart disease is classified as slowly progressive pathological structures cardiovascular system, so that the level of diagnosis of this condition is now quite high.Despite this, according to world statistics, a high level of mortality from acute coronary syndrome, which is the main manifestation of the atherosclerotic lesions of the coronary arteries.
Thus, atherosclerotic heart disease is a collective term, combining all cardiac pathology, at the origin of which is a violation of blood flow in the coronary vessels.
Causes of atherosclerotic heart disease
in the development of atherosclerotic heart disease as atherosclerotic vascular lesions at other sites, great importance is a combination of modifiable and immutable factors provocation available to the patient.Of course, genetic predisposition to the development of atherosclerotic lesions person eliminated may not, however, modification of lifestyle in the form of quitting, compliance hypolipidemic diet, normalization of glucose in the blood, weight loss, reduces the risk of provoking death from acute coronary events.
Thus, the combination of predisposing factors occurs an excess accumulation of cholesterol layers in the projection of the coronary arteries.The international community cardiologists opinion that atherosclerotic heart disease without hypercholesterolemia can not develop, because it is cholesterol is the pathological substrate of an atherosclerotic plaque.
symptoms of atherosclerotic heart disease
Considering the clinical variants of atherosclerotic heart disease, should be used to read that in the early stages of development of this pathology occurs completely asymptomatic.Pathognomonic clinical symptoms develop only in case of pronounced narrowing of the inner lumen of the coronary artery, and manifested in the form of a typical attack cardialgia or angina, disorders of the rhythm of cardiac activity, chronic circulatory failure, and even sudden infant death syndrome.
main pathognomonic clinical criteria of atherosclerotic heart disease is the appearance of the patient's frequent episodes of heart attack resulting from damage to the surface of atherosclerotic plaque and blood clot formation, which prevents normal blood flow.The main predisposing factor for the damage of plaque is a sharp increase in the level of catecholamines in the blood, which explains the development of the symptoms of a heart attack after excessive psycho-emotional stress.The principal difference between a heart attack when atherosclerotic heart disease from false angina and angina, it is considered that the result of an attack is the development of irreversible pathological changes in the structure of the heart muscle, which inevitably provokes the inhibition of its main functions.
Classic heart attack is an episode of severe pain syndrome localized in the projection of the left half of the chest with the characteristic radiating to the upper limb and neck.Type of pain in atherosclerotic heart disease similar to anginal attack, that is, pain is mostly a burning character.In addition to the severe pain syndrome patients with atherosclerotic heart disease, noted the growing respiratory disorders in the form of progressive dyspnea, increasing in a horizontal position.
In some situations, the development of classical acute coronary syndrome is preceded by the appearance of non-specific symptoms in the form of episodes of angina.Diagnosis "atherosclerotic heart disease" is impossible without a highly specific imaging techniques (roentgenopaque methods echocardioscopy, radionuclide techniques).
treatment of atherosclerotic heart disease
choice of technique for treating a patient suffering from atherosclerotic heart disease depends primarily on the severity of coronary artery occlusion and consists in the application of surgical treatment is radical removal of signs of impaired blood flow, as well aspathogenetic conservative treatment.Medical treatment for this disease is primarily used to prevent the progression of atherosclerosis is the use of drugs statin (oral Torvakarda in a daily dose of 10 mg).Treatment of coronary artery atherosclerosis involves a lifelong supplementation group of salicylates (Cardiomagnyl a daily dose of 75 mg), as well as prolonged intake holesterinsnizhayuschih drugs under the supervision of laboratory indicators of liver function.
Currently, the only effective method of leveling the manifestations of atherosclerotic heart disease is to conduct surgical treatment of coronary artery bypass grafting, the principle of which is to form a "workaround" to restore normal blood flow.This method of correction of coronary atherosclerosis has limited application, since the imposition of coronary artery bypass involves the operation open transthoracic access.
Currently, vascular surgeons are increasingly began to prefer alternative methods of surgical treatment of atherosclerotic heart disease, which include balloon dilatation, laser angioplasty and the establishment of an intravascular stent.
Despite the effectiveness of surgery in terms of elimination of existing atherosclerotic plaques, this method does not prevent further progression of atherosclerotic heart disease.To this end, in the postoperative period and throughout the life of a patient suffering from atherosclerotic changes in the coronary arteries should follow the specific recommendations of the nutritionist and life to take oral forms of drugs statin.
atherosclerotic heart disease - a doctor will help ?In the presence or suspected development of atherosclerotic heart disease should immediately seek the advice of such physicians as a physician and / or cardiologist.
